This cannon barrel stands as a monument in Cook Park on the shore of the Georges River. It is located near the mouth of the river at Botany Bay, in the southern suburb of Sans Souci. The barrel came from the HMS Wolverine, flagship of the Australian Squadron 1876-1881. HMS Wolverine was built at Woolwich dock, England in 1863 as a three masted steam corvette with 21 guns and a flush deck. When it arrived in Sydney it served as a training ship for the naval brigade. It was sold off in 1895 and when it became unseaworthy ended up in Auckland, New Zealand. It was dismantled at Brick Bay, later renamed Stanley Bay.
